Equestrian names

So despite being a name nerd, one area I'm kind of lax in is name meanings. A good friend who is a fairly accomplished equestrian is expecting a girl, and I wanted to see if anyone could help out with girl names to do with horses. I already know of a few--Philippa, Eponine, Rosamond & Cabalina. Any other suggestions? Cheers!

Thanks! I ran the list by her and she loved Alcippa and Etain, though she said Etain might be too masculine sounding. And your idea of winning mares was great (she liked Mariah, but wasn't sure it had enough of a tie), she now thinks Bellamy might be a nice choice, I think this was a horse that ran in the Kentucky Derby a few years ago. Any other suggestions?
